Mock Test's results vary wildly??

I am getting ready to take the programmer test Jan. 3rd. I have been using JPrep, the roundup and Marcus's mock test to this point and usually score between 75-85 on a fairly regular basis. Since Im a week away I bought the JWhiz and JQPlus tests. To my horror I got a 53 on JQPlus and a 35 on JWhiz......The questions on the JWhiz seem to be really intricate and really had me scratching my head saying "Why in the heck would anyone ever do that?" Ive got a week but this has kind of scared me.....Is there anyone else out there that has seen these two tests or taken them.....should I freak now or keep plugging along?

I recently bought both JWhiz and JQ+ before taking my exam. Before I took the exam I was averaging 96% on JWhiz and 89% on JQ+. You should try to work through all the exams if you have time (One week may not be enough).Once you are consistently scoring in the 80's, you will be ready for the test.

Hello DC, I passed the SCJP2 exam last week with 86%. I had a few questions that were very similar to questions asked in JQPlus. The first time I took a JQPlus practice test I scored 52% but I stuck with it until I was consistently getting post 85% in the random tests. The trick is to use it to identify and eliminate your weak points. I think Marcus tests are good for basic language fundamentals but for Threads, IO, Inner Classes, AWT, you need testing tools that are more rigorous. Try and do the more challenging mock tests such as JTips, Guoqiao Sun, Khalid Mughal, Bill Brogden, and http://www.go4java.cjb.net/, along with JQPlus they will really sharpen you up for the actual exam. As you approach your examination date do the simpler tests to boost our confidence i.e. JavaPrepare, Marcus Green 1/2/3, JCETs etc.
